IMPROVEMENT IN MACHINES FOR F ORWHNG FERRULES.

Specification forming part of Letters Patent No. 134,092, dated December17, 1872.

To all whom it may concern:

Be it known that I,W1LLIAM L. NEwsnAM, of the city of Philadelphia, inthe State of Pennsylvania, have invented certain Improvements inMachines for Shearing and Bending Metal Tube-Sockets, of which thefollowing is a specification:

My invention, in the first place, consists of a pair of dies connectedwith suitable slides, one of which is operated by means of a cam and theother by a crank, or other suitable mechanism. In the second place, itconsists of a table which has an upward movement so 'as to present theskelp at a convenient height to be transferred to the dies, and then adownward movement so as to be out of the way of the delivery of the bentskelp, the movements being givenby means of a cam-wheel on a revolvingshaft. The invention, in the third place, consists of a reciprocatingclamp for supporting the mandrel on which the skelp is pressed at theopposite side to the lowest die while it is giving the first pressure tothe skelp. After'this pressure is completed the clamp iswithdrawn out ofthe way of the delivery of the bent skelp. The invention, in the fourthplace, consists of a stripper, which has a forward motion imparted toit, to discharge the socket from the mandrel by means of a cam on one ofthe gear-wheels connected with the revolving shafts, which operate thedies, as hereinafter described. In the fifth place, the inventionconsists of an oscillating shear operated by a crank, with which thesaid shaft is provided, in such a manner as to scarf the skelp in properlength and of a suitable curve for welding.

Figure 1 is a front elevation of the machine when the dies are spreadapart to receive the skelp S. Fig. 2 is alike view when the lower die Ghas pressed the skelp against the lower side of the mandrel M. Fig. 3,Sheet No. 2, is a like view when the upper die G has completed thepressure. Fig. etis a side elevation of the machine. Figs. 5 and 6,Sheet No. 3, are views at right angles with each other of the shaft 0,provided with a crank wrist-pin, J, and cam-wheel Eh Figs. 7 and 8 arelike views of the shaft (J and cam-wheels E and E Fig. 9 is a face viewof the upper die G. Fig. 10 isa side elevation of the same. Fig.

11 is a side elevation of the lower die G. Fig. 12 is a face view of thesame. Fig. 13 is a side view of the mandrel M. Figs. 14. and 15 areviews, at right angles to each other, of the stripper N and oscillatinglever 0. Fig. 16 is an isometrical view of the shear-standard V. Fig. 17is a like view of the stationary ske-lpshear W and pedestal X. Fig. 18is a like view bf the oscillating shear T. Fig. 19 is a like view of thelink U Fig. 20 is a vertical section of the machine at the line a b ofFig. 4.

Like letters in all the figures indicate the same parts.

A is the bed-plate of the machine, and B B the housings. O and O arerevolving shafts for operating the dies, connected by means of thegear-wheels D I) and the intermediate wheel D on the shaft (3 The poweris applied by means of a pulley, or otherwise, on the shaft 0 The lowershaft 0, shown in detail in Figs. 7 and 8, is provided at its front endwith a cam-wheel, E, for giving a reciprocating movement to the slide F,the upper projecting edge of the recess a resting on the edge of thecamwheel. The shaft is provided at its upper end with the lower die Gand the cam E, for giving a like movement to the sliding yoke H,

which has on its upper end a horizontal bar,

I, on which the skelp is placed ready for being transferred to the dies.The upper shaft 0, ShOWII i eta l in Figs. 5 and 6, is provided at itsfront end with a crank wrist pin, J, for operating the slide F, havingthe upper die G connected at its lower end, the said wrist-pin operatingthrough the intermediate idler K in the opening a of the slide, as seenin Figs. 1, 2, and 3. The cam-wheel E is connected with the' slidingyoke H for operating the clamp L on its lower end for a support to themandrel M during the pressure of the lower die G. The upper die G isrepresented in detail in Figs. 9 and 10, and the lower die G in Figs. 11and 12.

On the mandrel M, which is represented in detail in Fig. 13, and back ofthe dies G and G, is a stripper, N, having projecting pins b b, whichbear against the bent skelp to discharge the socket from the mandrel asit IS forced forward by the lever O, which is hung on the fulcrum-pin cin the slotted projection d, as seen in Figs. 3 and a, the lever beingoperated by means of the sliding rod 1, which is forced forward by meansof the cam Y on the inner side of the gear-wheel D. The rod is returnedback into the position seen in Fig. 4.. by means of the spring It.

The stripper N and actuating'lever O are represented in detail in Figs.14 and 15.

The skelp S is out ready for the operation of the dies by means of theoscillating shear T hung on the crank wrist-pin e of the shaft 0, andone end of the connecting-link U, the other end of which has a jointconnection with the standard V, shown in detail in Fig. 16. Thestationary shear W is connected with the pedestal X, shown in detail inFig. 17. Aproper bevel curve for welding is given to the ends oftheskelps by means of the oscillating movement of the shear T.

The operation of the machine is follows: The shaft (3 and C beingrotated in the direction of the arrows while the die G is in itsdownward position, seen in Fig. 1-it being caused to descend by theeccentric part, from the point 1 to the point 2, of the cam-wheel Epassing under the part fof the slide Fthe shelp S is transferred fromthe horizontal bar I of the sliding yoke H, and placed with its endsresting in the rabbets g g of the lugs h It on the upper edge of theslide F ready to receive the pressure of the lower die. Then, by theaction of the cam-wheel E the yoke H is brought into its downwardposition, seen in Fig. 2, so as to hold the clamp L against the upperside of the mandrel M, to sustain the upward pressure of the die G. Theclamp is held in that position while the earn from the point 5 to thepoint l is passing over the part t of the slide 11 and the firstpressure is given to the skelp while the cam-wheel E, from the point 2to the point 3, is passing under the partf of the slide F, so as tocurve the middle part of the skelp S to fit the mandrel M, asrepresented. Then, by the action of the crank wrist-pin J upon the idlerK, the upper die is caused to descend and bend the ends of the skelp S,as seen in Fig. 2, thus completing the bending operation ready forwelding, the lower die Gr being held against the skelp during theoperation of the upper die, while the concentric part, from the point 2to the point 3 of the cam-wheel E, is passing under the part f of theslide F. When the dies are spread apart into the position they assume inFig. 1, the cam Y on the shaft (J strikes the rear end of the shaft 1?and forces the shaft forward, whereby the stripper N is caused to slideon the mandrel M and discharge the bent skelp from the mandrel, as maybe understood by Fi e. lVhen the cam leaves the end of the shaft thespring It returns it to its former position.

The skelps are cut to their required length by the shears abovedescribed, the crank-connection of the shear T with the shaft 0, and itslink-connection with the standard V giving a curve motion to thecutting-edge of the shear T, and causing it to scarf the edge of theskelp the proper curve for welding.

I claim as my invention- 1. The combination of the upper die G with theslide F, lower die G, and mandrel M, the said slide being operated bymeans of the crank wrist-pin J or other suitable mechanism,

substantially in the manner and for the purpose set t'orth.

2. The horizontal bar I for supporting the unbent skelp S, incombination with the dies G and G, substantially as described.

3. The clamp L, in combination with the slide H, mandrel M, and lowerdie G, the said clamp having a reciprocating movement imparted to it,substantially in the manner and for the purpose specified.

e. The arrangement set forth of the strippe N, mandrel M, lever 0, rod1?, and cam Y for discharging the finished skelp from the mandrel,substantially as described.

5. The oscillating shear T, in combination with the crank wrist-pine ofthe shaft 0, the eoni'iecting-link U, standard V, and stationary shear'W for cutting the skelps the required length and giving their ends therequisite scarf for welding, substantially as set forth.
